There is an OpenEHR presenation / paper for the MIE 2006 conference, tackling some of the differences HL7 / CEN and ISO work together on a 13606-HL7 v3 R-MIM that does the conversion, it is currently developed as an implementation guide. There are comments from the Netherlands to CEN about the 13606 (available at the CEN website) in which some brief comparison is included. Most people compare the 13606 OpenEHR materials with the HL7 RIM. However, that is the wrong level to compare, appropriate would be to compare with the HL7 v3 Care Provision D-MIM derived from the RIM, because this is focused on the EHR extract and on the full Record exchange message. In general: OpenEHR / 13606 RIM is the most generic / a-specific model level, could potentially be used for shipbuilding records, supermarkets and healthcare records HL7 v3 RIM is more detailed in such that it covers health care specific classes and relationships D-MIMs are made of the HL7 v3 RIM virtual bricks to become meaningful domain models derived from D-MIMs are the R-MIMs which are subsets for specific message purposes. on the detailed level the archetypes in CEN 13606 and in HL7 v3 the templates and R-MIMs for specific care statements, cover the smallest molecules of clinical data. examples of the latter can be found at www.zorginformatiemodel.nl A problem with the archetype approach (see the definition of this in open EHR and 13606) is that it does not address the clinical vocabulary which is included in HL7 v3 R-MIM approaches and it does not tackle the clinical knowledge base that explains why some data have to fit together and why a relationship has to be kept. (E.g. for scientific instruments and scales). Hope this helps, dr. William Goossen co- chair HL7 v3 patient care TC -------------- next part -------------- An HTML attachment was scrubbed...
